Male Fakra to Male DIN antenna adapter cable.

This is a passive adapter cable, not suitable for cars that need a phantom power supply to turn on the antenna amplifier.
Steering wheel control interface and universal patch lead (39-MB-A20/NTG1)
The cable adapts from the Quad-lock connector in the car to standard aftermarket ISO connectors. This replaces the need for a separate ISO radio replacement adapter cable. The CANbus steering wheel control interface is built in to the adapter cable for a plug and play installation This interface will allow the original audio control buttons on the steering wheel to work with the new aftermarket radio. The interface will work the volume and track skip buttons. The CANbus interface will also provide ignition, illumination, reverse gear, handbrake and speed pulse outputs. This interface is supplied with a universal patch lead. This links the steering control interface to the steering wheel control input on the back of the new stereo.
PLEASE NOTE: This interface is only suitable for cars with original basic NTG1 radios. Cars with the upgraded COMAND APS NTG1 radio will require a different interface.
